By deducting 0.5 from the lower class limit and 0.5 from the upper class limit, the class borders can be calculated by mean .

The arithmetic mean, often known as the average, of a dataset is the sum of all values divided by the total number of values (as opposed to the geometric mean). This is the most often used index of central tendency, sometimes known as the "mean." This result can be obtained by simply dividing the total number of values in the dataset by the sum of all the values. For calculations, it is possible to use both unprocessed data and data that have been merged into frequency table . Average refers to the average value of a number.

Answer: To find out how long it took the class to paint the whole mural, you need to first find out how many square feet the mural is. To do this, you can multiply the length and width of the mural together:

4.75 feet x 3.25 feet = 15.4375 square feet

You know that it takes 30 minutes to paint 1 square foot, so you can multiply the number of square feet by the time per square foot to find the total time:

15.4375 square feet x 30 minutes/square foot = 463.125 minutes

So, it took the class approximately 463.125 minutes to paint the whole mural. To convert it to hours, you can divide the minutes by 60:

463.125 minutes / 60 = 7.71875 hours

So, it took the class about 7.71875 hours to paint the whole mural.

Step-by-step explanation:

The width of the garden with an area of 70 square feet is 10 feet

An equation consists of numbers and variables linked together by mathematical operations to form an expression.

The area of a field the amount of space occupied by the field. The area is the product of its length and width. It is given by:

Area = length * width

Let w represent the width. The length is 3 feet longer, hence:

Length = w + 3

Area = length * width

Area = (w + 3)(w)

But the area is 70 ft², hence:

70 = (w + 3)(w)

w² + 3w = 70

w² + 3w - 70 = 0

w = 7 feet

Length = w + 3 = 7 + 3 = 10 feet

The width is 10 feet

An intercept is a point on the y-axis through which the slope of a line passes in mathematics.

An equation for a line stated using a single point on the line and the line's slope is a straightforward definition of point-slope form. The slope is defined as the rise over run, or the proportion of the change in the y values over the change in the x values, and the point form is denoted by the letters (x, y).

These statistics are here. When a linear equation is expressed in this way, it has the benefit that the values for m and b are the slope and y-intercept, respectively. Consequently, it is easy to graph the line that the equation depicts. M stands for slope, and B for intercept.

An intercept is a point on the y-axis through which the slope of a line passes in mathematics. A place where a straight line or a curve intersects the y-axis is designated by its y-coordinate. The equation for a line, y = mx+c, which has m for the slope and c for the y-intercept, represents this.

The percentage decrease will be 23 percent.

A game streaming service is having an end-of-the-year sale.  They are offering discounts on everything, from new memberships for their service to gaming controllers. You purchased a new membership with this service for $46.20 for the year, that was originally $60, Therefore, the percentage decrease can be calculated as follows:

percentage decrease = original value - new value / original value  × 100

original value = 60 dollars

new value = 46.20 dollars

percentage decrease = 60 - 46.20 / 60 × 100

percentage decrease = 13.8 / 60 × 100

Jackson used 1 1/6 quarts of blue paint more than black paint to paint the picture.

Quarts is an imperial and US customary unit of volume equal to a quarter of a gallon, or two pints. It is used in the US to measure dry and liquid ingredients and is especially popular for measuring beer and other beverages. One quart is equal to 946.35 milliliters, or 32 ounces. Quarts are also used in the US customary system to measure dry and liquid ingredients, as well as fuel and other liquids.

In order for Jackson to have used 5/6 quarts of blue paint and 1/2 quart of black paint, he would have used 1 1/6 quarts of blue paint more than black paint. To calculate this, one can add the two fractions together and convert the result to a decimal. The sum of 5/6 and 1/2 is 11/6, which is equal to 1.83.

Using the concept of ratio and Pythagoras theorem, the length of the diagonal is 22.95 in

A ratio is a way of comparing two or more quantities. It is a mathematical expression that shows the relationship between two or more numbers. The ratio can be written in different ways, such as 4:3, 4/3 or 4 to 3.

In this problem, we have the ratio of width to the height of the screen and we can use Pythagoras theorem to determine the length of the diagonal.

width = 20 in

ratio = 16 : 9

width = (16 / 25) * x

20 = 16/ 25 * x

Total length = 31.25

The height of the screen can be calculated as;

height = 9 / 25 * 31.25

height = 11.25

Furthermore, Bank Y has no monthly fees as long as Henry uses his check card less than 6 times per month, which he is likely to do. Additionally, Bank Y offers online banking services, which Henry is interested in.

Bank X has a monthly fee of $7 if the balance stays below $500, which Henry is likely to incur as he usually only has $300 in his account. Bank Z has a $5 monthly fee regardless of the balance, which is not ideal for Henry.

On solving the provided question, we can say that angle 1 + angle 2 = 180 => 11x - 30 + x = 90 => x = 10; angle 1 = 80; angle 2 = 10

An angle is a form in Euclidean geometry made composed of two rays, called the angle's sides, that meet at a point in the middle known as the angle's vertex. In the plane where the rays are placed, two rays can produce an angle. An angle is also produced when two planes intersect. They're known as dihedral angles. In plane geometry, an angle is the form that two rays or lines with a common termination might take. The Latin word "angulus," which means "horn," is where the English word "angle" comes from. The two rays, also known as the sides of the angle, have a common termination known as the vertex.

here,

angle 1 + angle 2 = 180

Answer:

3/2

Step-by-step explanation:

Find 2 easy to read points: (1, -3) and (3, 0).

slope = (difference in y)/(difference in x)

slope = (-3 - 0)/(1 - 3)

slope = -3/(-2)

slope = 3/2

Step-by-step explanation:

usually, when asked about the equation for a line, we give it in slope-intercept form :

y = ax + b

"a" is the slope, "b" is the y-intercept (the y-value when x = 0).

the graph tells us the y-intercept right away : 6

the scope is the ratio

y coordinate difference / x coordinate difference

when going from one point on the line to another.

I recommend to always look for points with integer coordinates (the line goes through a vertex of a grid square).

the y-intercept gives us the first point

(0, 6)

and then I see easily at the other end of the visible line :

(4, 10)

between these 2 points

x changes by + 4 (from 0 to 4).

y charges by + 4 (from 6 to 10).

the slope is then +4/+4 = 1

so, our equation is

y = x + 6

If  a player hits a ball while a bird is flying across the field. The intersection points of the equations represent: C the time when the height of the ball and the bird are the same.

Intersection points  can be defined as the points in which two parallel lines meet each other.

Given data:

Height of the baseball over time = h = –16t² + 65t

Height of a bird over time = h = 8t + 20

Where:

t = time in seconds

h = height in feet

–16t² + 65t =  8t + 20

-16t² +57t -20 =0

So,

t = -57 ±√57² -4×(-16) × (-20) / 2× (-16)

t = -57±√3249  -1280/ -32

t = -57 ±√1969 /-32

t = -57 + 44.373 / -32

t =  -12.627 /-32

t =.395

And

t = -57 - 44.373 / -32

t =  -101.373 /-32

t =3.168

Based on the above of the height of both the baseball and the bird, the time when the height of the ball and the bird are the same  are the points were the two lines intersect.

Therefore the correct option is C.

The equation where t varies inversely with S then  t= [tex]\frac{19.2}{S}[/tex].

What is equation?

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

Here according to the question t varies  inversely with S then,

=> t ∝ [tex]\frac{1}{S}[/tex]

To remove inverse we need to include constant. then,

=> t = k×[tex]\frac{1}{S}[/tex]

=> t = [tex]\frac{k}{S}[/tex]

Now put t=2.4 and S=8 then

=> 2.4 = [tex]\frac{k}{8}[/tex]

=> k = 2.4×8 = 19.2

Then the equation is t= [tex]\frac{19.2}{S}[/tex].

Hence the equation where t varies inversely with S then  t= [tex]\frac{19.2}{S}[/tex].
